Application flied July 21,

To all lv/0m it muy con Be it knovn that l, .l N l-l. Contains, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented new and usefulImprovements in .Pumps, of Whichthe following is a. specification.

My invention relates to pumps of the type generally utilized for drawingrelatively small quantities lof liquid from a storage tank; theprincipal objects of my invention being to generally improve upon andsimplify the construction of existing types of similar pumps, to providea pump that is of relatively simple structure thereby permitting it tobe manufactured at relatively low cost, and further to provide simpleand eliicient means for catching and retaining all drip or overflow fromthe pump spout or the container into which the liquid is discharged, andfor returning said drip and overflow to the storage tank.V

Further objects of my invention are to provide simple and efiicientmeans for locking the pump While not in use, thereby preventing theunauthorized use of the pump, and yfurther to provide pump `of thecharacter described with means for preventing foreign substances, suchas sand, dust, 'and Water rfrom entering the return tube and passinginto the storage tank.

-Vllith the foregoing and other objects in view7 my invention consistsincertain novel features of construction and arrangement of parts thatwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawings, in which:

Fig. 1 is an elevational view of the pumpv with parts thereof ,insection.

Fig. 2 is a vertical section ,taken approximately on the line 2 2 ofFig. 1.

3 is a horizontal section taken approximately on the line of 1.

Referring Vby numerals to the accompanying drawings which illustrate a.practical embodiment of my invention, l() designates the cylindricalbody of the pump, the same being preferably formed from a section ofmetal tubing of proper size, and arranged von he ends ofsaid cylindricalbody is an upper head l1 and the tower head 1Q, the same being.connected and maintained in assembled relation by suitably located tierods 13.

Secured in any suitable manner to the lower head l2 and dependingtherefrom is a preferably of .the d.W

short tubular housing lll from which projects laterally a tubular neck15 that terminates vin a. horizontally disposed pan 16. This pan is ofdisc-like form and is provided with an unstanding marginal flange 17.Beinovably .arranged Within the pan 16 is a section 18 of reticulatedmaterial', such as Wire netting, the same serving as a support for thecontainers that receive liquid discharged from the pump spout. Hinged topan V16 and preferably ata point adjacentlto tubular member 14 is acover platev 19 for the pan 16, and arranged on the underside of saidcover plate adjacent to its edge is a gasket or packing member 20 thatisadapted to rest directly on top of flange 17 and provide a. practicallyair and dust proof joint when the cover plate is closed.

rllhe cover plate19 is retained in lclosed position upon pan 16 byasuitable latching device 2l that is preferably located diametricallyopposite the hinged point of saidl cover plate. The lovver end oftubular member lllis directly connectedL to the upper end of a tube 22that extendsV downwardly `and thence laterally to the lower` end of aliquid storage tank (not shown).

l Formed integral with or fixed tothe lower portion of head l2 andpositioned in the upper portion of tubular` member 14 -is a cage- 25 toWhich is connected the upper .end of the pump tube 26 that v extendsdowntva-rd` through the verticalgfleg of tube- 22, Aand arranged in theupper portion of said cage 25 an u Wl dly open-in inlet checkvalve 28type. Arranged for reciprocatory movement .Within the cylindrical vbody'10 lof the pump is a piston 2S) carrying on its periphery a cup packingmember 30, and-said piston being provided with one or more openings 31that are normally cloed by an upwardly opening check valve 32 preferablyof the disc type. Connected in an y suitable manner to the upper end ofthe piston 29 is the lower end of a pump rod that is arranged kforreciproca-tion :through a gland or stuffing box S-l on lthe top of `head1l. Pivotally connected to the upper end of pump rod v33 is one.

end of a pump operating-lever' thatis provided on its lower yor outerend With a handle 35, and there being a ring 37 formed on the loiver endof said handle. Pivotally connected to a bracket that projects outwardlyeat 27 upon i Aich normally rests slow movements.

from lower head 12, is the lower cud of a link 38, the upper end ofwhich is connected to the intermediate portion of lever 35 by a rel-Y Vatively short link 33, Pivotally mounted on the lower portion of link 38is the inner end of a loop 39 that is adapted to receive the ring 37 onthe lower end of lever 35 when the latter occupies a substantiallyvertical position, as illustrated in Fig. 3. When ring 37 is thusengaged through loop 39,'the operating parts ofthe puinpmay beeffectively locked by the application of the hasp of a suitable padlockIi() through theV ring 37. Screw seated in the upper head 11 is theinner end of a tubular spout 41, the outer end of which is bentdownwardly so that it occupies a position a suitable distance above thecenter or" pan 16.

The operation of my improved pump is as follows: v

Lid or cover plate 19 is swung upward so as to uncover pan 16, and thecontainer that is to receive the liquid discharged fromA spout 41 isplaced on the reticulated member 18. Handle 36 is now manually engagedand lever 35 is manipulated so as to reciprocate piston 31 within thepump cylinder, which action draws liquid from the storage tank upwardlythrough tube 26, and which liquid after passing through the alternatelyopening check valves 28 and 31 passes through the upper portion of thepump cylinder and discharges through spout 41 into vthe receptaclepositioned on pan 16 Any overflow from this receptacle and likewise anydrip from the spout l1 will pass from pan 16 into tubular member 15, andfrom thence said drip or overflow liquid will pass back to the storagetank through pipe 22` After the receptacle has been removed yfrom thepan 16, cover plate 19 isswung downwardly on to the top of said panthereby effectively preventing foreign matter, such as dust, water andthe like from entering the return tube 22 'that leads to the storagetank. the pan 16 is such as to prevent relatively thin liquids fromsplashing outwardly over the edges of' the pan, and likewise ,fornreventing relatively heaiy liquids from piling up and overflowing as aresult. of their Further, the capacity Vof the return tube 22 is muchgreater than the capacity of tube 26 that carries the liquid to thepump, and which arrangement prevents the drip pan from overflowing inthe event that the flow of' liquid'from the pump is directed from thenozzle into the drip pan.Y Such construction insures the quick return ofall characters of liquid to point of storage.

The depth and general form of lWhile my improved pumpV maybeadvantageously employed wherever Y relatively small quantities ofliquid are periodically withdrawn from a storage tank, it is'par-Aticularly adapted for use for the handling of fuel, lubricating andilluminatingv oils, and its use in connection therewith affords arelatively high degree of safety, economy,

cleanliness and efficiency'.V y

y lt will be understood that-minor changes in size, form andconstruction of the various parts of my improved pump may be made andsubstituted for those herein shown and described without departing fromthe spirit ,of my invention, the scope of which is set forth in theappended claims.` l claim as my invention:

1. A pump comprising a body, a piston-v movable in the body andincluding a rod ex'- tending from the body, a lever pivotally connectedto the outer end of the piston rod, a Y

rod pivotally connected to the body, a link pivotally connecting thesecond' rod with Y said lever, an eye formed on the `free end of thelever, and a keeper pivoted on' the second rod and adapted to pass oversaid eye so that Vwhen a lock engages the eye, the keeper will be lockedto the lever.

2. A pump comprising a body, la 'piston movable in the body andincluding a rod eX- tending` from the'body, a lever pivotally connectedto the piston rod, a rod pivotally con'- /nected to the body, a linkpivotally connecting the second'rod with said lever, Van eyel formed onthe free end of the lever, and means associated with the Veye forlocking the lever against movement. Y

3; A. pump comprising a body, a piston movable in the body and includinga rod eX- teiiding from the body, a lever pivotally connected to thepiston rod, afrod pivotally coun nected to the body, a link pivotallyconnectf ing the second rod with said lever, an eye formed on therfreeend of the lever, and coacting means on the lever and second rod forlocking the lever against movement.
